R: mistake in SOAP envelope XMLSchema

Hi Christopher,
 
thank you for your answer.
Actually I was talking about SOAP 1.1 (not 1.2) and about this XMLSchema:
 
http://schemas.xmlsoap.org/soap/envelope/
 
which (as stated in the comment) appears to be the official SOAP 1.1 schema. (Am I wrong?)
I agree with you: SOAP 1.2 does not allow the encodingStyle attribute to appear on the envelope element, but SOAP 1.1 (and its schema) should!
 
Best regards,
 
Alessandro Pira

Alessandro, 

The quoted text you cite is pretty clear. I have emphasized using CAPS. 

"SOAP 1.2 DOES NOT ALLOW the env:encodingStyle attribute to appear on the SOAP env:Envelope, whereas SOAP 1.1 allows it to appear on any element. SOAP 1.2 specifies specific elements where this attribute may be used." 

Additionally, from the SOAP1.2 specification [1]: 

"The encodingStyle attribute information item MAY appear on the following: 
1.        A SOAP header block (see 5.2.1 SOAP header block <http://www.w3.org/TR/soap12-part1/#soapheadblock> ). 
2.        A child element information item of the SOAP Body element information item (see 5.3.1 SOAP Body child Element <http://www.w3.org/TR/soap12-part1/#soapbodyel> ) if that child is not a SOAP Fault element information item (see 5.4 SOAP Fault <http://www.w3.org/TR/soap12-part1/#soapfault> ). 
3.        A child element information item of the SOAP Detail element information item (see 5.4.5.1 SOAP detail entry <http://www.w3.org/TR/soap12-part1/#faultdetailentry> ). 
4.        Any descendent of 1, 2, and 3 above. 

The encodingStyle attribute information item MUST NOT appear on any element other than above in a SOAP message infoset." 

The soap:encodingStyle attribute is NOT permitted to be included in on the soap:Envelope element. Therefore, the schema is correct.
